Description
Monitoring voltage relay, 3-phase HRN-43, HRN-43N
galvanically separated supply AC 230V, AC 400 or AC/DC 24V, memory, adjustable hysteresis and delay, 2 x independent output
monitoring 3-phase mains:
- voltage in 2 levels 160-276 V (3x400/230 V) or 280-480 V (3x400 V)
- phase asymmetry
- phase sequence
- phase failure
function MEMORY - manual reset, RESET button on front pannel
HRN-43 - for circuits 3x400 V (without neutral)
HRN-43N - for circuits 3x400/230 V (with neutral)
2 output relays, selectable function of 2nd relay (independent / parallel)
fixed (t1) and adjustable (t2) delay to eliminate short voltage drops and peaks
galvanically separated supply voltage AC 400 V, AC 230 V, AC/DC 24 V
output contact: 2x changeover 16 A / 250 V AC1
